Final answer:
Without specific inventory purchase and sale figures from Question 7, the calculation of Red Rover's cost of merchandise inventory on hand after the sale on June 14 using FIFO cannot be accurately determined.
Step-by-step explanation:
In order to calculate Red Rover's cost of the merchandise inventory on hand using the FIFO (First-In, First-Out) method, we would need the specific figures of inventory purchased and sold up to the date of June 14. Without those details from Question 7, it is not possible to provide an accurate calculation of the cost of inventory on hand after the sale on that date. In FIFO, the oldest inventory costs are assigned to the cost of goods sold first, leaving the most recent inventory costs to represent the value of the inventory still on hand. As the sale patterns and exact costs of products sold before June 14 are not provided, we cannot compute the remaining inventory value. Hence, we cannot confidently select between the provided options A. $510, B. $2,400, C. $1,004, or D. $936.
